The former Destiny’s Child singer was forced to get tough after Misha – who is one of three girls remaining in the competition – slated vocal coach Anne-Marie Speed and others behind the scenes of the show.

And Rowland also reprimanded Misha for boasting to the other contestants that she had already won the show, while members of the production team had branded her ‘the diva from hell’, according to The Sun.

‘Misha is out of control and Kelly just snapped,’ a source told the paper. ‘She told her that unless she packs it in she’ll be sent packing herself.’

‘It’s one thing to give it the big ‘I am’ with the other wannabes but it’s totally out of order to be rude to people who work on the show. Kelly is a lovely woman but when the s**t hits the fan she gets tough – and she got very tough with Misha.’

Misha impressed the judges with her version of Rolling In The Deep on last weekend’s show

The Mancunian teenager was reportedly ‘shell-shocked’ after Rowland’s telling-off, and has since been made to apologise to crew members on the show.

Misha impressed the judges on last weekend’s show with her rap-fuelled interpretation of Adele’s Rolling In The Deep.

She was chosen by Rowland, along with Sophie Habibis and Janet Devlin, to proceed to the next stage of the live finals following an emotional results show in which fellow girl Amelia Lily was eliminated.

Saturday’s show will see the contestants perform love songs in their latest bid to remain in the competition.
